Primary intermediate in oxidative hair dyeing |
| abstract |
5-Nitroisatin is reacted with sodium hydroxide to produce an alpha-keto acid sodium salt that is reduced with borane-tetrahydrofuran complex and then hydrogenated to produce 1-(2,5-diaminophenyl)ethylene glycol, a novel compound useful as a primary intermediate in the production of oxidative hair dyes. |
